Nicky Zann’s cover for the reissue of the Gilded Man must rank as one of the creepier examples of retro-vintage. International Polygonics did an entire series of classic mystery reprints in the late 1980s and early 1990s, most of them with quirky, offbeat covers, a number of them done by Nicky Zann. Unfortunately it seems that the company went out of business around 1995. However, their books are still very much available.
